- ing systems and particularly to a system in -andt which a timing. device is used, so that elevators may be given starting signals automaticall e object of this invention is to provide a single dispatching device under the control of the dispatcher, which may be arranged to control the starting signals for any number of cars.

A feature of this device is the arran ement whereb any number of cars may be dispatche automatically from the ground floor at predetermined intervals, which intervals may be varied at will.

Another feature lies in the rovision of means for dispatching any or a of the cars from the top floor at predeterminedindependently variable intervals. Afurther feature resides in that indications of the condition of the car starting signals are also given at the dispatchers desk.

A still further feature is the division of the interval for a complete up and down trip into either erglal up and equal down trips or longer up t is feature may be accomplished by keepingmthe complete trip time constant, or it may varied to any desired value.

These features, together with the particular adjustment features in the device itself, will become more apparent when taken in connecmounted at a dispatchin tion with the accompanying drawings wherein Fig. 1 represents the complete equipment plosition for controlling the dis atching o a ank of cars Fig. 2 is a ront view of the dis atchers unit, partly in section, to show the rictional mounting of the discs;

Fig. 3 is a side view of the unit;

Fig; 4 is an end view of the unit with the slider and handle shown in section; and Fi 5 is a schematic arrangement of the circuits involved.

One embodiment of the invention, as set forth in the drawings, consists preferably of a dispatchers position or board from which two signals may be given in each car, one for the car to start from the ground floor and one an down trip, and vice versa V This invention relates to elevator dispatchfor the car to start from the top floor. In

order to indicate to the dispatcher the condition of the signals of each car, there is provlded at his position a series of signals actuated simultaneously with the car si als.

' There is further rovided a position indicator so that the location of each car may be ascertained. 1 I

By means of this invention it is possible to operate the starting signals automatically and to re ulate the interval between the starting of al the cars from the ground floor or top floor. Furthermore the schedule speed of the cars may be determined, and the length of time consumed in a round trip may be either evenly divided between the u and down trips or a larger portion may be a otted to one or the other as\ desired.

Any number of carts may be so controlled I and others be ut into service or taken out of service and t e starting intervals properly adjusted.

In Fi 1 a motor 1, whose speed may be set at any esired constant value by means of a rheostat 2 in its field or armature circuit, is suitably coupled at 3 to reduction ears, havin any desired ratio, enclosed in ousmg 4.

he shaft 5 of the reducing gears carries one of a pair of bevelled gears 6 which drives by means of the other bevelled gear 7 a shaft 8. The latter is rotatably mounted in suitable bearings 9 and 10 carried by supports 72 and 73, which are secured to a mounting anel by means of bolts and nuts 74 and 75. he bearin s 9 and 10 permit shaft 8 to be longitudina 1y 'slidable so that it may be disengaged from driving gear 6 by liftlng handle 1'1,.whose cam-like surface 12 en ages the rounded concave tip 13 of shaft 8. e latter is held in its raised position, since its tip 13 is seated in a concave portion Mat the extremity of cam surface 12. The rotation of shaft 8 may thus be stopped while its driving means continues to revolve.

Suitably keyed to shaft 8 at re ular intervals are flanges 15, the number of anges correspondin to the number of cars in the bank. Frictional y mounted on the shaft and adj acent the flanges are discs such as 16 and 17, the-former having wider diameters than the latter. Special springs 102 around the shaft tend to maintain the flange 15 and the two discs 16 and 17 in engagement, so that they will all rotate with the shaft in the same relative position in which they have previously been placed. In the surface of each disc is mounted a pin 28, projecting far enough beyond the surface to actuate one of two rows of contact buttons 40 to 45 and 46 to 51 upon each revolution of the'shaft.

The two rows of contact buttons 40 to 51 are mounted on blocks 76 and 77 on opposite sides of shaft 8, the contact buttons on one side of the shaft being arranged in staggered relation to those on the other side. I

Supports 72 and 7 3 are projected outwardly, as at 78 and 79, respectively, to hold a rod on drum 90 contains two indentations 180 80 in parallel relation to shaft 8. Mounted on rod 80, which may be of any desired cross section, is a slider 81 having a handle 82 and a projection 83. The latter is adapted to be moved along rod 80 and to engage any two adjacent pins, for example 28 and 29, thus alining them.

' At its lower portion there is keyed to shaft 8 at 84 a flanged wheel or drum 90, having in its outer surface a plurality of rows of indentations. A red 91, mounted adjacent the I drum 90 sup orted at 92, carries a slider 94 so having a pro ection 95 to engage the indentations on drum' 90- and a knurled handle 96 for easy adjustment. The first or upper row apart; the second contains three indentations, 120 apart; the third, four 90 apart; the

- fourth, five 72 apart; and the fifth, six 60 apart. With shaft 8 disconnected from its driving gear, slider 94 may be movedalong rod 91 until it is opiposite any desired row on wheel 90. The sha is turned to permit projection 96 to engage each of the indentations cation of this invention.

Referring to Fig. 5, a source of power on feed wires 103 and 104 maybe connected through double pole switch 52 to the field and armature of the'constant speed motor 1, hereinbefore described.

Each of the six cars contains two lamps, one, preferably white, 53, as an up signal and the other, preferably red, 54, as a down signal. These lamps are connected at one si by means of conductor 55 to a double pole switch 56 leading to a source of current.

position. A double pole switch 59, also 10- Lamps 53 and 54 at the other side are connected respectively in series with similar lamps 57 and 58, located at the despatchers cated at the dispatching position is interposed between the lamps. and the'dispatching unit.

The contacts 40 to 45, inclusive, are connected by means of conductors 60 to 65, inclusive, to the up lamps 53 and 57 while the contacts 46 to 51, inclusive, are connected over conductors 66 to 71, inclusive, to lamps 54 and 58, so that one of these lamps will be energized every time a contact is closed.

Suppose it is desired to dispatch six cars at regular intervals, so that each car will consume half of its running time in going up and the other half in coming down. Handle 11 is moved upwardly, disengaging the gear 7 of shaft 8 from gear 6 on driving shaft 5. The

shaft 8 will then be free to'be hand rotated with its convex tip 13 seated in the concave portion of cam surface 12. Slider 94 is then until its pin 28 engages its contact 46. The

shaft 8 is then moved until the next indentation in the row is in engagement with prowardly along bar 80 until'its projection 83 is directly over the first two discs 16 and 17,

which, it should be noted, control the 0011- tacts for the signals of car 1.

The shaft is then turned so that the projection 29 of the second disc 17 is brought into alinement with that on disc 16, the former being held stationary, due to the engagement of its pin 28 with projection 46, and the latter being brought up until its pin 29 just touches projection 83. The slider 81 is then moved upwardly and the same operation. is performed for each pair of contact pins. It is thus evident that all six of the up contact pins are spaced 60 apart from each other,

and that all six of the down contact pins are also 60 from each other, but each up contact pin is 180 from the corresponding down contact pm.

Obviously means other than those 'ust described may be employed for setting the scheduling apparatus, the use of the slider 81 being merely one convenient and reliable method, but any other means which may be adopted by a person skilled in the art is intendedto come within the scope of my invention as defined in the appended claims.

The dispatcherv may now start the signals by lowering shaft 8 into engagement with its driving shaft 5 by means of handle 11.

As soon as pin 29 strikes its contact 40, a

circuit may be traced from positive batteryon conductor 105, conductor 106, contact 40,

conductor 60, switch 59, lamps 57 and 53 in j series to negative battery on conductors 55.

These lamps are illuminated as an indication to the operator of car- 1 to start from the ound floor, and to the dispatcher to inform in that car 1 has been signalled to start. When shaft 8 has rotated pin 31 on disc 19 strikes its contact 41 and a circuit is closed over conductor 61 for lamps 53 and 57 for car 2. Closure of contact 42, 60 later, lights the lamps for car 3, and so on similarl for the other cars. When shaft 8 has ma e a half revolution, pin 28 causes the closure of contact 46 and battery on conductors 105 and 106, through contact 46, over conductor 66, lights lamps 54 and 58 as a signal for car 1 to start down. Theother cars are also signalled in order.

By proper cross connection at either switches 59 or contacts 40 to 51, inclusive, the cars may be dispatched in any desired order.

In large buildings during the so-called morning and evening rush hours, best service is obtained by dividin the round trip up into unequal intervals. or example, in the morning, the up trip takes much longer than the down trip since most all the passengers are entering the building andfew leaving. In the evening, conditions are the reverse. Each of the lar e discs 16, 18, 20, 22, 24 and 26 as shown for isc 22 in Fig. 2, is calibrated, so that instead of lining up the pins as above described, they may be shifted in either direction a definite percentage with respect to their corresponding small discs 17 to 27, inelusive. It is ap arent that different percentages may be xed for different cars also if desired, since the discs are independently adjustable. v

If, at periods of light load, only a few of the cars are in operation, the switches 59 for the cars out of service are opened and the discs for the remaining cars set to give closures at regular'intervals. This is accomplished b moving slider 44 up along drum 90 to the row containing the number of indentations e ual to the number of cars in service, and t en setting the discs in the manner set forth above. The (11805 for the cars cut out will merely rotate idly, since the signal circuits are open at switches 59.

If desired, variousadditional and supplemental signals and indications may be iven by merely adding more contacts and pins to the discs and more signals or indicators to the car. For example, by placing pins at the proper intervals, each'makmg a separate contact, a light with the number 5 associated therewith could be illuminated when the car was due at the fifth floor, a light with number 10 when due at the tenth floor, number 15 light when due at the fifteenth and so forth- Instead of numerals various colors may be used. In this way the operator can exercise extremely intelligent control over his car; and the necessity of continual communication with the starter either through starters signals or telephonic announcements, is avoided.

Other embodiments may readily su gest themselves to those skilled in the art an the invention is not to be limited to the disclosure herein but is appropriately set forth in the ap ended claims.
